THADDEUS R. BAKER, OF INDIANAPOLIS, INDIANA.

MEANS FOR ATTAGHING- BGLSTE R- SPR-INGS.

To. all whom it may concern Be it known that l. 'lnaonnus R. BAKER,

a citizen of the United States, residing at Indianapolis, in the county of Marion and State of Indianzu have invented certain new and useful l]ll])]O/G1Y\GI1BS in lifleans for Attaching Bolster-Springs, of which the :l'ol-. lowing is a specification.

The object of this invention is to provide means for securing conical s iringsto wagon :bolsters, between the latter and the bed or load-carrying portion 01E a vehicle, in a ren'iovable manner in order to provide a ready means for converting a springless wagon into one wherein the load will be spring supported. I accomplish the above object by the means illustrated in the accompanying drawing, in whichv Figure 1 is a perspective view of a wagon bolster with my invention shown in operative position thereon, and Fig. 2 is a top plan view of one end of the same bolster and spring mechanism illustrated in Fig. 1., with the exception that the upper horizontal plate is removed.

Like characters of reference indicate like parts throughout the several views of the drawing.

The bolster for either the frontor rear aXle of any desired and well known form of wagon is of the usual construction and the load-supporting bed or. platform, whichis usually supported upon the bolster between the standards 4. is not shown.

Conical springs 55, here shown as two in number and of usual construction. are {astened upon a base-plate 6. The base-plate 6 is of metal. of approximately the same width as the top of the bolster and extends from one standard l of the bolster to the other and sutliciently beyond each standard to form a locking notch which will receive and hold the standard when the metal in the end of the plate removed for this purpose. The metal where the notches tor the standards are formed is removed for the reception of the standards by being bent into a loop toward the middle of the plate but is not detached at its inner end from the plate. The loop 7 thus formed is bent around a cross-bar 8 formed in a base-extension 9 of the spring 5. The length of the base-eaten sion 9 is .suilicient to position the conical spring 5 suitably remote from the standard 4: to properly support the load and afford. a sui able bea i g f r p g Specification of Letters Patent.

The material oi the spring 5 is further .clmtinued beyond the cross-bar 8 but in a direction causing it to pass under the bottom convolution of spring 5 forming a. member 10 upon which the spring 5 rests and by which it is partially supported. The member 10 is continuedsubstantially the same distance on the other side of the spring 5 to ward the middle of the bolster andis bent to term a second cross-bar l1 which 155 held under a loop 12 formed out o[ a tongue punched up from the material of the plate 6. The cross-bar 11 terminates in an end hook 153 whiclrprovents the longitudiiuil witlr drawal oi the crossbar from loop 12.

A. hearing plate 14: similar to the plate 6, with its enq s notched 111 like manner to en gagethe standards 4 is loosely positioned between said standards upon the pair oil. srnings 5. This plate is a metal. one and is principally for the purpose ot protecting the wooden wagon bed. to be supported by the sp igs, from wear. The mechanism. above .9 .ribed, including the plate 1.4: as shown in Fig. 1. is ready to receive the wagon. bed or other load-supporting memher (Ill the wagon which is placed upon the plate 1% between the standards t in subly the same manner as it was preplaced in direct contact with the it is obvious that my invention is. readily removable and can be used when desired or requiredand at other times can be omitted. While I. have described. my invention with more or less minuteness as regards details of constructirm and arrangement and as being embodied in certain precise forms I do not desire to be limited thereto unduly or any more than is pointed out in theclaims. O11 the contrary. l contemplate all rn'oper changes in form. construction and arrangement, the omission of innnaterial elements, and the substitution of equivalents, as circunrstances may suggest or necessity render expedient.

I claim:

1. In a. device for the purposesspecified, a base-plate, one or more coiled springs mounted on said plate, each spring having an extension of its lower end made in the direction of the adjacent standard and bent near the standard to form a cross-bar transverse to the bolster, said extension latter on the opposite side of the bolster from the starting place of said spring extension and thence continued and bent to form a second cross-bar resting upon the bolster upon the opposite side of the spring from. said cross-bar, and loops formed out of the material of the base-plate engaging said spring base-extensions whereby the latter are secured to the baseplate. Y In a device for the purposes specified, a,

latter on the opposite side of the bolsterfrom the starting place of said spring eX tension and thence continued and bent to form a second cross-bar resting upon the bolster upon the opposite side ot' the spring from said first crossbar, loops formed out of the material of the base-plate engaging the cross-bars of said spring base-extensions whereby the latter are secured to the baseplate, and a bearing plate resting upon said spring or springs. v

7 The combination with a bolster having a standard near each of its ends, of a baseplate on said bolster having end notches to receive the standards, one or more coiled sprin s mounted on said base-plate, each spring having an extension of its lower end made in the direction of the adjacent stand ard and bent near the standard to form a, cross-bar transverse to the bolster, said eX tension passing thence under the bottom convolution of the spring and supporting Copies 0! this patent may be obtained for five cents each, by addressing the Commissioner 0! Patel",

the latter on the opposite side of the bolster from the starting place of said spring extension and thence continued and bent to form a second cross-bar resting upon the bolster upon the opposite side of the spring from said first cross-bar, and loops formed out of the material of the base-plate and engaging each of said two opposite the cross-bars of base-extensions of each spring.

4. The combination with a bolster having a pair of standards one at each end, of a base-plate on said bolster having end notches to receive the standards, a pair of coiled springs mounted on said base-plate, each spring having an extension of its lower end made in the direction of the adjacent standard and bent near the standard to form a cross-bar transverse to the bolster, said extension passing thence under the bottom conrolution of the spring and supporting the latter on the opposite side of the bolster from the starting place-of said spring extension and thence continued and bent to form a second cross-bar resting upon the bolster upon the opposite side of the spring from said first crossbar, loopsformed out of the material of the'base-plate engaging the crossbars of each base-extension, and a bearing plate having its ends notched to receive the bolster standards, said plate resting upon said coiled spring. I

in witness whereof, I have hereunto set my hand and seal at Indianapolis, Indiana, this 19th day of March, A. D. one thousand nine hundred and fourteen.
